What to do when your guinea pigs mate dies?

I had two guinea pigs, Bill and Bobby, but recently Bill has passed away. Now that Bobby is by himself I have noticed he has stopped eating and isn’t as happy as he used to be. Does this mean I should get him another friend?

I am sorry to hear that Bill has passed away. Guinea pigs are very social animals, and do pine when they are alone. Bobby has probably stopped eating because he is lonely, and is craving the companionship of his own kind. Guinea pigs thrive with one or two companions, so I would definitely recommend getting a friend for Bobby to fill the void Bill left behind.

Many vets can routinely desex guinea pigs, so you don’t have to worry them mating if you were to get a desexed female guinea pig friend for Bobby. Bonding guinea pigs tends to be a lot easier than bonding rabbits – allow them to meet, and if they don’t immediately fight, they are fine as a pair. Ideal pairings are one desexed male and 2 desexed females. Note it is never appropriate to house rabbits and guinea pigs together.

It is also important to make sure Bobby and his new friend have enough space to interact and show natural behaviours. The key to Bobby’s happiness is catering to his social needs by having a friend, enough space to ‘popcorn’, burrows to hide, and levels to climb. In no time Bobby should be eating again, and back to his normal self!
